USB VBUS not routed

On the Network Gateway the VBUS from the USB host is connected to a test point next to the USB connector. For a USB device to comply the USB specifications, the device must sense the VBUS and not communicate, enable pull-up or pull-down on the USB data lines before VBUS is applied from the host.

Workaround: If designing a USB device with the Network Gateway as a reference, connect voltage limited VBUS to a GPIO pin. VBUS is 5V, GPIO tolerates 3.3V ! The Linux OS must also be patched to use the GPIO signal.
